Fact family for trigonometry identities sine, cosine, tangent
This math skill teaches how to utilize the relationships between sine, cosine, and tangent in trigonometry to form fact families. These relationships allow for calculating unknown sides of a triangle using the ratios of the known sides.
🎙️
Let's explore the fact families for the basic trigonometry relations
🎙️
Sine is opposite over hypotenuse, and we can calculate hypotenuse as opposite over sine
🎙️
Cosine is adjacent over hypotenuse, and we can calculate adjacent using cosine times hypotenuse
🎙️
And tangent is opposite over adjacent, so we have a similar set of calculation options
